Abstract
An output stage (1) for a digital RF transmitter is provided. The output stage comprises: an input adapted to receive an input signal (RFin, b7-b0) to be transmitted; a plurality N of power amplification sections (S1, S2, S3, S4); and an output (A, B) providing an output voltage signal. Each of the N power amplification sections (S1, S2, S3, S4) is arranged to receive the input signal (RFin, b7-b0) and comprises a transformer (T1, T2, T3, T4) adapted to provide a respective output signal. Each transformer comprises a primary stage and a secondary stage; the secondary stages of the transformers (T1, T2, T3, T4) of the N power amplification sections (S1, S2, S3, S4) are combined such that a combined output voltage signal of the output stage is provided. The N power amplification sections (S1, S2, S3, S4) are adapted such that the input signal (RFin, b7-b0) is latched by clock signals (clock1, clock2, clock3, clock4) comprising different phases.
